Khokhlov - Zabolotskaya - Kuznetsov (KZK) nonlinear parabolic wave equation describes the acoustic pressure changes in the nonlinear and dissipative medium along the sound beam. This equation is solving numerically. On the basis of the finite difference method computer programs have been worked out. These programs allow to conduct different numerical investigations. The paper presents a mathematical model of finite amplitude wave propagation problem. The results of numerical investigations refer to influence of discrete model parameters on accuracy of numerical calculations are studied.
